Hi,Can check if the current NXLog Manager can support RHEL 8.8?And any roadmap to support RHEL9 in future? ThanksRegards, Billy

I have a very small (Read - no budget) project that NXlog would be a perfect fit for. Parsing, reformatting, and moving logs from a third party app to our Splunk server. I have a config that is simple and would work perfectly - except I did not realize until today that the CE does not support HTTP headers. (I had been using the EE documentation apparently) I found this out via google search on this old thread:https://nxlog.co/community-forum/t/648-adding-custom-header-om-httpWhich was 4 years ago, and mentioned that HTTP header support is not in the CE yet. Are there any plans to add this? I seems like pretty basic HTTP functionality, even more so than HTTPS/SSL support (which must have been far more involved to implement). Without any idea on pricing at all on the EE (again, zero or close to it budget) and no “in between” edition, it seems like a shame that I cannot make this work with the CE.Any ideas? An alternate way to get logs into Splunk using the CE would also work for me. Any help greatly appreciated!

We have a Linux host we have installed nxlog-ce-3.2.2329_rhel7.x86_64.rpm with yum on. The install did not create the modules folder and it seems we have none of the required files. Is there a way that this all needs to be separately installed? Is it possible this nxlog-ce-3.2.2329_rhel7.x86_64.rpm package did not install fully?

hi,First of all I would like to know if NXLOG compatible with Windows server 2019. I have trouble with the performance of nxlog on windows 2019 while on 2012 everything is fine.The logs do not go up instantly even though the configuration is the same and there is no issue with the network.Does anyone knows what the issue might be?Thank you for your answers.

Hi Experts,I am reaching out to seek assistance with the installation of the NXLog Agent on my AWS EC2 Linux instance. I have encountered some challenges during the installation process and would greatly appreciate your guidance and support.The AWS EC2 instance I am using is running Amazon Linux version 2023. Here are the details of my Linux distribution:- Name: Amazon Linux- Version: 2023- ID: amzn- ID_LIKE: fedora- Version_ID: 2023- PLATFORM_ID: platform:al2023- PRETTY_NAME: Amazon Linux 2023- ANSI_COLOR: 0;33- CPE_NAME: cpe:2.3:o:amazon:amazon_linux:2023- HOME_URL: [https://aws.amazon.com/linux/](https://aws.amazon.com/linux/)- BUG_REPORT_URL: [https://github.com/amazonlinux/amazon-linux-2023](https://github.com/amazonlinux/amazon-linux-2023)- SUPPORT_END: 2028-03-01I kindly request your assistance in determining the correct RPM package I should download for this particular distribution and version of Linux.https://nxlog.co/downloads/nxlog-ce#nxlog-community-editionis there any documentation or resources that I can refer to for guidance on the installation process.Appreciate any help. 

Hi All,We would like to check what could be the cause when getting the below error message in nxlog.log when using port 514?ERROR couldn't connect to tcp socket on logs-01.loggly.com:514; A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. INFO connecting to 192.168.1.1:514 INFO reconnecting in 2 secondsWe are from SolarWinds Loggly and helping a customer to identify the cause as to why they are getting the above error message. From our documentation, we already advised them in editing the configuration file as "Administrator", this means that you should actually open up text editor as Administrator, but the issue still persists. Reference: https://documentation.solarwinds.com/en/success_center/loggly/content/admin/troubleshooting-nxlog.htm#Check-Connection The customer is using a latest version of NXLog Community Edition (nxlog-ce-3.2.2329). Is this a bug?  

Is it possible to perform a file deletion on the end of the file in the community edition with something like the below configuration?<Input csv>     Module          im_file    ReadFromLast    True    SavePos         True    PollInterval    300    File        'file/location'    # Parse the CSV events     <Exec>             csv->parse_csv();     </Exec>      <OnEOF>         <Exec>             file_remove(file_name());         </Exec>         GraceTimeout  10     </OnEOF></Input>

I have a setup with nxlog to collect audit log files that come to me daily. Each day the file name changes.I noticed that the incoming files are not sent to my remote SIEM, only the first one after restarting the NXLOG service.Below is my NXLOG configuration using the im_file and on_tcp modules.Would anyone have an idea how to resolve this? define ROOT C:\Program Files (x86)\nxlog Moduledir %ROOT%\modules CacheDir %ROOT%\data Pidfile %ROOT%\data\nxlog.pid SpoolDir %ROOT%\data LogFile %ROOT%\data\nxlog.log LogLevel INFO ####################################################################### EXTENTIONS ####################################################################### <Extension _gelf> Module xm_gelf </Extension> <Extension _json> Module xm_json </Extension> <Input auditoria> Module im_file File "E:\Dataside\SIEM*.json" ReadFromLast False SavePos False </Input> <Output graylog> Module om_tcp Host 10.100.8.113 Port 5555 </Output> <Route auditoria-to-graylog> Path auditoria => graylog </Route>

Would like to check where should i change the file for RHEL 8? I found the below link but doesn't work for rhel 8. Common issues :: NXLog Documentation This scenario requires edits to the service file or an override. To check NXLog system limits, use the following command:$ cat /proc/$(cat /opt/nxlog/var/run/nxlog/nxlog.pid)/limitsOn Systems not using /proc, check the system’s open file limit:$ sysctl kern.maxfilesTo adjust limits for nxlog, create /etc/systemd/system/nxlog.service.d/override.conf and add the following definition:[Service] LimitNOFILE=100000Update the service settings with:$ systemctl daemon-reload

I am trying to migrate our functional Enterprise config to Community on other devices.Thanks,Paul 

Hi I'm working on a setup for collecting IIS logs and send them to Graylog. Here I stumbled into a problem with refering to fields with a dash in the field name. I would really like the fields to have prober w3c names in greylog, so I dont wanna remove those dashes. In the CSV module I have: <Extension w3c> Module xm_csv Fields $date, $time, $s-ip, $cs-method, $cs-uri-stem, $cs-uri-query, $s-port, $cs-username, $c-ip, $csUser-Agent, $cs-referer, $sc-status, $sc-substatus, $sc-win32-status, $time-taken, $X-Forwarded-For FieldTypes string, string, string, string, string, string, integer, string, string, string, string, integer, integer, integer, integer, string Delimiter ' ' QuoteChar '"' EscapeControl FALSE UndefValue - </Extension> And in my input def i have: <Input iis_dodpdownload> Module im_file .... Exec if $raw_event =~ /(^#)|((keepalive.html).*(\s-\s200\s0\s))/ \ { \ drop(); \ } \ else \ { \ w3c-&gt;parse_csv(); \ $EventTime = parsedate($date + &quot;T&quot; + $time + &quot;+00:00&quot;); \ $SourceName = &quot;IIS&quot;; \ $Message = $cs-method + &quot; &quot; + $cs-uri-stem + &quot; &quot; + $sc-status; \ } </Input> The line $Message = $cs-method + " " + $cs-uri-stem + " " + $sc-status; results in a parser error. If I change field names to not contain dash character then it works. I also tried to surround with curly braces but it just returns a new parse error. How can i refer to those fields/vars or escape them? Hope someone knows:-) Best regards, Peter Meldgaard

I am receiving some logs from network devices that don't include the source IP or host in the log message. How do I add $MessageSourceAddress to the message so I can identify its source?I've tried Exec $raw_event = $raw_event +$MessageSourceAddress;But that does nothing. What is the correct syntax for this?

I have encountered an issue that in nxlog agent i can connected to the nxlog manager. But in the nxlog manager i couldn't see any agent in the list. 

Hello there, We are currently getting PowerShell transcript logs in one of our Windows WEF Collectors. Each log is been generated as a .txt file following the following naming convention: PowerShell_transcript.$deviceName.$RandownNumber.txt. For example this is how the folder looks like: G:/PowerShell_logs/ PowerShell_transcript.device1.qww.txt PowerShell_transcript.device2.fgd.txt PowerShell_transcript.device3.hjj.txt The issue I am having is that the content of each .txt file is arriving to the SIEM at one line at the time instead of arriving all the lines on the same event. This is the content of one of the PowerShell transcript file.
